Composite admixture regenerated micro powder and preparation method thereof
The invention relates to the technical field of concrete regenerated micro-powder, and discloses composite admixture regenerated micro-powder, which is prepared from the following raw materials in parts by weight: 30 parts of regenerated micro-powder, 10 parts of fly ash, 15 parts of a water reducing agent, 30 parts of silica fume, 40 parts of an anti-freezing agent, 5 parts of lime, 10 parts of gypsum and 10 parts of an epoxy adhesive. According to the composite admixture regenerated micro-powder and the preparation method thereof, the water reducing agent is added, after the regenerated micro-powder is added, the particles of the regenerated micro-powder are dispersed, the workability of the regenerated micro-powder can be improved, the unit water consumption is reduced, and the purpose of saving water is achieved; besides, the water reducing agent can improve the flowability of the regenerated micro-powder mortar and reduce the unit cement consumption, so that the production cost of the regenerated micro-powder concrete is reduced, the freezing point of the regenerated micro-powder mortar can be effectively reduced by adding the anti-freezing agent, and the anti-freezing performance of the regenerated micro-powder mortar at negative temperature is greatly improved. In addition, the early strength of the concrete and the mortar can be improved by 80% or above, the later strength is not reduced, and the strength of the concrete is improved.
本发明涉及混凝土再生微粉技术领域，且公开了一种复合掺合料再生微粉，包括以下重量份数配比的原料：再生微粉30份，粉煤灰10份，减水剂15份，硅灰30份，防冻剂40份，石灰5份，石膏10份，环氧胶粘剂10份。该复合掺合料再生微粉及其制备方法，通过添加的减水剂，加入再生微粉后对再生微粉颗粒有分散作用，能改善其工作性，减少单位用水量，实现了节约用水的目的，且减水剂可改善再生微粉砂浆的流动性，减少单位水泥用量，减少再生微粉混凝土的生产成本，通过添加的防冻剂，能有效降低再生微粉砂浆的冰点，大大提高再生微粉砂浆在负温下的抗冻性能，并能使混凝土、砂浆的早期强度提高80％以上，后期强度不降，提升了混凝土的强度。
